Ammonia reacts with boron trifluoride to form a stablecompound, as we saw in Section 8.7. (a) Draw the Lewisstructure of the ammonia–boron trifluoride reaction product.(b) The B—N bond is obviously more polar than the C—C bond. Draw the charge distribution you expect on theB—N bond within the molecule (using the delta plus anddelta minus symbols mentioned in Section 8.4). (c) Borontrichloride also reacts with ammonia in a similar way tothe trifluoride. Predict whether the B—N bond in the trichloridereaction product would be more or less polar thanthe B—N bond in the trifluoride product, and justify yourreasoning.
